Cisco C1112-8P Full Product Description

1. Short Overview

Suffix Breakdown

• C1112: Hybrid DSL-enabled mid-tier ISR platform of Cisco 1000 Series with integrated VDSL2/ADSL2+/G.FAST modem and combo fiber-copper WAN
• 8: Integrated 8-port full Gigabit copper LAN switch
• P: 6 out of 8 LAN ports support PoE / PoE+ power output with total shared 120W PoE power budget

Core Differentiators

1. vs pure Ethernet C1111-8P: C1111-8P only offers dual copper/combo Ethernet WAN without DSL modem; C1112-8P adds a built-in multi-profile DSL WAN port for copper telephone line broadband access, ideal for DSL service providers and legacy copper access branchesCisco.
2. vs Wi-Fi variant C1112-8PW: Wireless models integrate internal 802.11ac Wave2 WLAN AP; base C1112-8P is wired-only without Wi-Fi hardware.
3. vs rugged industrial C1109 M2M series: C1109 targets wide-temperature industrial M2M with pluggable cellular PIMs; C1112-8P is commercial-grade optimized for DSL ISP and enterprise office deployments with high PoE density.
4. vs entry-level C1101-4P: C1101-4P lacks SFP fiber slot, DSL modem and high PoE capacity; C1112-8P provides hybrid DSL+fiber dual WAN and expanded 8-port PoE LAN for multi-device workloads.
5. vs legacy ISR G2 C880/890 DSL routers: Older DSL ISRs run classic IOS without native SD-WAN, limited crypto acceleration and lower PoE power capacity; C1112-8P uses modern IOS XE, hardware VPN acceleration, flexible fiber SFP uplink and scalable mixed PoE design.
